To all whom it may'conoem:

'Bcit known that I, Gnonen H. Bnosti, a and a resident of Chicago -Hei.ghts, in and State of Illinois, vented c'ertain new and useful Improvements in Universal Joints, ofwhioh thefol lowing is a specification! I My 'nventi-on' relates in universal joints adapted-foriuse in cou pling .or joining shafts, for the purpose-0f transmitting motion from one for which universal joints of-this type are applicable, the objects being to providea device of this character which'will be free likely to catch the from projecting parts clothing, or injure a person- Whdmay .come

' into. contact with it; to provide a universal purpose for which vit is designed,'and one joint in which the oil for. lubricating ,purposes will be retained within the sam e because ofi-ts structural features, and withoutthe provision of special oil-retaining means; to provide 'a universal joint which willbe simple in construction and effective for the which may be, readily manufactured and easilyassembled and disassembled; and to provide such other improvementsin and relati'nfgto universal joints as are hereinafter disclosed and shown in the drawing nccompanying-and forming a part of this 'application.-

view, my invention consists in the improved universal joint shown in the accompanying drawing and hereinafter described and claimed, and .in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention re lates. i j

Inthe drawing: Figure 1 is a view showing my improved universal joint in side elevation, with a portion broken away to illus trate certain features of the, interior construction thereof; Fig. 2 a section upon a longitudinal central plane indicated by the line 2-2, Fig. 1; Fig. 3 is into it; Fig. 5 is a v ew ing pin in perspective;

a similar view showing the two. principal members of the joint inclined with reference I to one another; Fig. 4 -1s a view showing the-ball member of the joint as seen looking Fig. 6'is a view 3 .Speeifieation oL-I tters Patent; Application as m n 18, 19111." Serial No. 621,926.

upon a plane at right angles to the'plane of Fig. 6, and Figs. 8 and 9 are views similar to Figs. 6 and 7 and showing still another formof my improved universal joint.

In thedrawings, 10 is'the hollow socket. member of my improved universal joint, and 11 a vsleeve portion formed preferably inone piece therewith and to which the end of :a sh-aft, not shown, is connected, as by means of a recess-12 into which the end of said shaftiprojec ts. ,"lhe socket member 10 is formed-in two parts, and is shown as provided with a detachable portion 13,

member 10, the inner surface of the latter and detachable portion 13 thereof being spherical-in form. Diandetrically across the socket member extends a' pin let, the ends of which lie in recesses 15, formed in the innersurface-thereof, the ends of said pin being preferably cut away as shown at 16, Fig. 5, in order to prevent the same from rotating in the bearings for the ends thereof formed by the recesses 15.

The said ball member is "provided with two diametrically disposed slots 20 within which the'pin 14 lies when the parts are properly assembled, the slots being long enough, (see Figs. 1, 6 and 8) to permit of an-upward or downward movement of the ball member, as will be understood.

In 'Figs d and 7 the pin 21 .is shown as surrounded by a square sleeve 22 which of another form of myimproved Fig.1 7 1s a' similar view preferably .in threaded engagement with the The saidpin' is thus held in positionby the detachable The reference character .17 designates a.
